Who said that graphing calculators were dead in the smartphone era? Certainly not Texas Instruments -- if anything, it's showing that there's still plenty of life left in dedicated math machines. Its new TI-84 Plus CE is 30 percent thinner and 30 percent lighter than the regular Plus, making for a...

Getting to Mars is never going to be cheap. But a couple of mathematicians have figured out how to shave some significant bucks off the price tag. Rather than fly to the red planet when its orbit brings it closest, the craft will "meet" it on the way. The strategy is called ballistic capture and i...

If WiFi can track a heartbeat through walls, why can't I get internet in my corner bathroom? Jason Cole was trying to figure that out too, but unlike me, he's a PhD student in physics. So he mapped his own apartment and assigned refraction values to the walls (shown above), then applied so-called ...

D-Wave has long wanted to show that its quantum computing technology is the real deal, and it may have just come closer to proving its case. The company now says that its computer has calculated Ramsey numbers, or solutions to optimization-based math problems that are sometimes difficult to find u...

In the wake of NASA successfully landing a robot rover on Mars recently, you might be wondering what happened to the NASA-themed MMO titled Astronaut: Moon, Mars and Beyond. The first thing that's happened to it is that the project has been retitled Starlite. Project Whitecard Studios Inc. hopes ...

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. It's a beautiful world we live in. And, while the sweet and romantic part is debatable, strange and fantastic is not. Our universe is one populated by non-planetary celestial bodies with their own...

Is gaming the answer to the math- and science-related apathy plaguing American school kids? Some folks at MIT think so, and a new press blurb outlines how the institute is developing an MMO designed to further science, technology, engineering, and math (STEM) education.
"In contrast to the way...

Astronaut: Moon, Mars, and Beyond has been in the news a lot lately, but just who are the folks behind the educational MMO from NASA and Project Whitecard? A new piece at Gamasutra sheds a bit of light on that as well as a few more details about the project as a whole.
"I'm originally a develo...

A computer solving a Rubik's cube? P'shaw. Doing it in 10.69 seconds? Been there, record set. But to crack one of any size? Color us impressed. Erik Demaine of MIT claims to have done just that -- he and his team developed an algorithm that applies to cubes no matter how ambitious their dimensi...

The hyper-ambitious folks at DARPA are totally over the current state of military data collection, and they're pretty sure they know how to fix it: teach sensors how to think. Well, they've got an idea how to fix it, but they've put out a call for mathematician to do the dirty work. The Mathematics ...

The Antikythera Mechanism is what you call truly old school technology. Argued to be the world's oldest known computer, this ancient Greek invention was used some time circa 100BC to calculate and "predict celestial events and eclipses with unprecedented accuracy." Skipping past the two millennia i...

A new record has been broken in the field of mathematics by a team of researchers and a super computer working on creating a very long version of Pi. The team, led by Nicholas Sze of Yahoo!, used the company's Hadoop cloud computing tech to break the previous record by more than double, creating th...

Sure, you could prove as-of-yet-unsolved mathematical problems (why hello there, P≠NP), but where's the entertainment value for the rest of us? Cue Futurama staff writer Ken Keeler, who used his PhD in "Math Blasters (in N Dimensions)" to create and verify a theorem that served as the crux of th...

If you don't know the major problems facing mathematics and computer science, you might not be familiar with the problem of P versus NP. In short, it's a problem which asks, "if 'yes' answers to a yes or no question can be quickly verified, can they also be computed quickly?" Many computer scientis...

Russian mathematician Grigori Perelman has apparently turned down a one million-dollar prize which he was awarded in March by the Clay Mathematics Institute. Perelman was awarded one of seven million dollar prizes for solving a "millennium" problem -- the Poincaire conjecture -- which had been puzz...

Man has striven for centuries to build a better mousetrap, but in the digital age, mice are the least of our worries. No, the modern day rat race requires a better alarm clock instead, and lord knows we've seen plenty, from tickers that chomp your change to clocks that give you target practice. W...

We've been getting a generous look under the hood of Champions Online courtesy of designer Brian Urbanek, with the second part of his system-focused developer diary now available. The first part covered the progression and improvement of a player's heroes, while this diary focuses on the mechanics...
